RADI TOR.

T 0 all whom it may concern: 7 I

Be it known that I, PIERRE J. H. BER: NARI), a subject of the King of Great Britain, residing .at Montreal, Province of Quebec, Canada, have inventedcertain new and useful Improvements in Radiators; and

I do hereby declare that the following is' a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich itappertains to make and use the same...

The present invention relates to improvements in radiators and appertains more partieularly to water and air column type adapted for use in connection with steam or hot water heating systems.

The principal object of the invention is to provide a radiator of the water and air column type which can .be manufactured in standard sections, so as to be easily mounted in any required length suitable for rooms of any size. Another object of the invention is to provide a-radiator of this character in which, should a pipe or tube become'worn or broken, another one may be easily-and readily substituted therefor, and one. which will be comparatively inexpensive in its cost of manufacture, thereby rendering the same commercially desirable.

Another object of the invention is to provide a radiator having the advantages of being demountable and at the same time having a greater heat radiating surface.

A still further object of the invention is to provide novel mounting means for the series of steam and heated air circulating tubes.

WVith the above and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings has been shown a simple and preferred form'of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but the right is hereby reserved to any changes, alterations or modifications to which recourse may be had that come within the scope of the claims without departing from the spirit of the invention or sacrificing the efliciencyof the same.

The invention has been illustrated in its Specificatiouof Letters Patent. Patented BT31, 15, 1921, Application filed January 2,.19211. .:Seria1 vNo. 349,103; 1 1' i 7 preferred embodiment in the accompanying drawings, wherein,

Fig. 2 is an endelevation of the same;

Fig.3 is afragmental planelevation of the end casting of the radiator formingthe sub ectmatter of the present invention Fig. 4 ma partial vertical section-0n line if-4; of Fig-37;, g .Fig. 51s a transverse vertical section on line 5- 5 of Fig. 3; and Fig.5 is a transverse vertical section on line 6-6 of Fig. 3.

"In carrying out the present. invention,

reference beinghad to the drawings in detail, ,there: are provided a plurality of tubes 10, arranged transversely'in series of four 1n this instance. Each of the tubes 10 comprising the series, is exteriorly screw threaded at the upper and lower ends and saidthreaded portions take into similarly threaded openings provided'in the upper and base coupling members 11 and 12.

These coupling members 11 and 12 are of integral constructionand formed with .in-

terior chambers- 13 7 into 1 which open the tubes 10. 1 I

Qoupling members 11 and 12, centrally of thelr confronting side portions, are formed with flat offsets 14, which, when the said members are connected together, space the HIELJOI part of the said coupling members from each other.- V

Openings are provided in the flat otl'sets 14, which communicate with the interior chamber 13, and nipples 15, of double wedge configuration, have their opposite ends 16. disposed in the offset openings of said cou phng members 11 and 12 and serve the function of connecting the members 11 and 12 together and for establishing communication between the successive chambers 18.

Likewise openings are provided in the upper and lower walls 17 and 18 respectively of the upper and base coupling members 11 and 12, and said openings are threaded for the reception of the inner tubes 19 which latter extend downwardly through the upper coupling members 11. tubes 10 and the base coupling members 12: The upper and base" couplings 11 and 12 may be connected together at their offset portions 14 by pressure in using nipples 15 or by means of ordinary screw nipples 15 to insure perfect sealing of the same the heating element.

at these points, and the entire radiator unit is supported upon the floor surface by teet 20 cast integral with the end coupling members.

Pipes 21 and 22 are connected by an elbow 23 and lead from the steam or hot water supply, the pipe 22 having a threaded end which takes into a nipple, not illustrated, in the base coupling 12. A valve 24: in pipe 21 controls the said supply to the radiator unit and a similar pipe 25 is connected to the top coupling 11 for further circulating It will therefore be seen that the hot water or steam will circulate upwardly through the tubes and downwardly through the upper coupling members 11 to the base member 12. The heating element in this manner has contacting engagement in a tortuous path through the radiator unit with the inner tubes 19, through which the air freely circulates. As the sa1d lnner tubes 19 are open at both ends, the air constant supplyof heated air will arise from the radiator unit.

By this construction, a greater heating area of the radiator is effected, as not only do the inner tubes 19 heat the air but, like- 7 relation thereto.

wise the outer tubes 10 heat the air in the manner of the ordinary type ofradiators, and a radiator mountable by unit is provided.

Having thus fully described my invention, what I claim, as new and desire to secure by Letters Patent is 1. In a radiator the combination of upper and lower coupling members, arranged adjacent each other, nipples connecting said coupling members, vertical tubes passing through the opposite sides of the upper and lower couplin members and surrounding tubes connected to the adjacent sides of said upper and lower coupling members and surrounding the first mentioned tubes placed in r 2. In a radiator of the type describedthe combination of a plurality of upper and lower coupling members, arranged in engagement, and provided with alining openings, nipples extending into said coupling members and engaging the openings therein,

and affording a communication between 5 said coupling members and connecting said couplinghmembers together, tubes connecting the adjacent sides of the coupling members and communicating therewith,

through openings formed in the adjacent sides of the coupling members and additional tubes passing through these first mentioned tubes and entirely throughboth sides of said coupling members.

In witness whereof I have hereunto set PIERRE JOSEPH HENRI BERNARD.
